Rafflesia Patma (Rafflesiaceae): Notes on Its Field Study, Cultivation, Seed Germination and Anatomy

Rafflesia spp. (Rafflesiaceae) have a strategic value from both scientific and conservation viewpoints. To date only very few attempts have succeeded in growing the species ex situ and the main protection measures have been by in situ conservation. More detailed studies are required to understand the relationships between Rafflesia spp. and their host plants in order to improve their management and conservation. Studies on the anatomy, in vitro culture and seed germination in connection with conservation have been conducted in the Bogor Botanic Gardens. Effort to transfer Rafflesia patma to an ex situ conservation area has produced some flowers. However, we encountered a bigger challenge to maintain the long term presence of R. patma in ex situ conservation, since a high number of individuals is required to make the viable population

First Lunar Occultation Results from the 2.4 m Thai National Telescope equipped with ULTRASPEC

The recently inaugurated 2.4\,m Thai National Telescope (TNT) is equipped, among other instruments, with the ULTRASPEC low-noise, frame-transfer EMCCD camera. At the end of its first official observing season, we report on the use of this facility to record high time resolution imaging using small detector subarrays with sampling as fast as several $10^2$\,Hz. In particular, we have recorded lunar occultations of several stars which represent the first contribution to this area of research made from South-East Asia with a telescope of this class. Among the results, we discuss an accurate measurement of $\alpha$~Cnc, which has been reported previously as a suspected close binary. Attempts to resolve this star by several authors have so far met with a lack of unambiguous confirmation. With our observation we are able to place stringent limits on the projected angular separation (<0\farcs003) and brightness ($\Delta{\rm m} > 5$) of a putative companion. We also present a measurement of the binary {HR~7072}, which extends considerably the time coverage available for its yet undetermined orbit. We discuss our precise determination of the flux ratio and projected separation in the context of other available data. We conclude by providing an estimate of the performance of ULTRASPEC at TNT for lunar occultation work. This facility can help to extend the lunar occultation technique in a geographical area where no comparable resources were available until now.Comment: Accepted for publication in Astronomical Journa

Multimodal fusion : gesture and speech input in augmented reality environment

Augmented Reality (AR) has the capability to interact with the virtual objects and physical objects simultaneously since it combines the real world with virtual world seamlessly. However, most AR interface applies conventional Virtual Reality (VR) interaction techniques without modification. In this paper we explore the multimodal fusion for AR with speech and hand gesture input. Multimodal fusion enables users to interact with computers through various input modalities like speech, gesture, and eye gaze. At the first stage to propose the multimodal interaction, the input modalities are decided to be selected before be integrated in an interface. The paper presents several related works about to recap the multimodal approaches until it recently has been one of the research trends in AR. It presents the assorted existing works in multimodal for VR and AR. In AR, multimodal considers as the solution to improve the interaction between the virtual and physical entities. It is an ideal interaction technique for AR applications since AR supports interactions in real and virtual worlds in the real-time. This paper describes the recent studies in AR developments that appeal gesture and speech inputs. It looks into multimodal fusion and its developments, followed by the conclusion.This paper will give a guideline on multimodal fusion on how to integrate the gesture and speech inputs in AR environment

Weight and length at birth are the good indicators to evaluate the possibility of survival, growth, and chronic disease as adults. This analysis aims to assess the effect of maternal nutritional status as pre-pregnant and pregnant on birth weight and length of infants at risk of chronic disease in adulthood. The design of this study was a prospective cohort, starting from pre pregnancy, during pregnancy until infant birth. Data analysis used multiple logistic regression. The result showed that 6 percent of infants birth weight &lt;2500 g and 26.4 percent of infants birth weight to chronic disease risk (&lt;3000 g). Approximately 30.1 percent of infants stunted at birth (&lt;48 cm) and 62.6 percent infants at birth length &lt;50 cm (standard WHO 2006). Mean of height pre-pregnancy is 151.9±5.6 cm and mean of body mass index (BMI) pre-pregnancy is 20.6±3.1 kg/m2. Maternal BMI pre-pregnancy is a major risk factor for birth weight infants &lt; 3000 g after controlled by maternal height, weight gain during pregnancy, maternal age, parity, diarrhea, energy and protein intake and sex of the baby. Maternal height is a major risk factor for infant birth length (&lt;50 cm) after controlled by pre-pregnant maternal BMI, maternal age, parity, weight gain during pregnancy, diarrhea, energy and protein intake. Conclusions, maternal nutritional status is a risk factor for pre-pregnant weight and birth length

Perbanyakan Amorphophallus Titanum Becc (Araceae) Dengan Teknologi in Vitro

Propagation of Amorphophallus titanum Becc (Araceae) via In Vitro Technology. Amorphophallus titanum is a unique plant with gigantic inflorescence and radiating corpselike odorl and therefore has become a botanical flagship and attract visitors. Its existence innature may be endangered due to habitat conversion that reduce population size required for cross pollination to occur. Propagation via non-conventional technique is much needed for the resulting planting material to be exchanged among botanical garden or even traders. Mass propagation using in vitro technology has been successful. An improvement of the propagation method has been developed by incorporating high level of cyitokinin BA of 1-2 mg/l in the medium for shoot proliferation and lowering it to 0-0,1 mg/l for shoot elongation. Shoot elongation is effectively influenced by age and the phase of medium whereas the liquid phase induced the enlargement of the shoots significantly without even promoting any hyperhidricity.The plantlets produced survive acclimatization
